[Feature Request] Library Manager: Allow selecting multiple libraries to update

[SlickNet]

Updating libraries one by one can be tedious if you have a large set of libraries to update at any time. Please provide a way to have the software iterate over all or a set of them to do the update, instead of having to select each one of them and deal with laggy UI.

Thanks for your feature request @SlickNet. We already have a feature request for the "update all" component you requested: #4438, so lets use the existing issue for that request and make this one solely for the "selecting multiple libraries to update" part of your request, which I don't see an existing request for.

It is possible to achieve both requests via a feature that provides a list of updatable libraries, which can be individually selected or deselected, then all selected libraries installed in a batch.
